Coils

Our coil selection software

Computair’s coil selection program offers design, rating and selection for coils and heat exchangers.

Designed with the coil manufacturer in mind, it allows the user to configure the system with fundamental design details, heat transfer data and costing information. Coil configurations can be added to, deleted or altered as required.

Typically the coils are constructed from copper primary tubes, with aluminium or copper fins attached by mechanical bonding. The coils are selected by means of fundamental equations working in conjunction with an operator-amendable database.

All coil types are accommodated:

Hot water
Cold water
DX
Steam
Condenser
Run-around coil design package

SELECTION AND RATING OPTIONS

All coils apart from the run-around system can either be selected (designed to achieve a particular duty), or rated (the performance of a given coil).

VARIETY OF GEOMETRIES AND TUBE SIZES

We have a wide range of geometries and tube sizes, allowing the user to configure the system and add different options on request.

BLACK BOX/DLL/WEB SERVICE CREATION FOR 3RD PARTY SOFTWARE

Our coil software offers the facility to develop your own black box/DLL or web service that can be incorporated into 3rd party client software.

CALCULATION ENGINE FOR NEW REFRIGERANTS AND MICROFIN TUBES

We have completely re-written the internal heat transfer co-efficient calculation for direct expansion and condensing coils. We use a US database REFPROP to obtain our heat transfer information, which allows us to calculate the performance of all modern refrigerants. New refrigerants can be added on request.
